The notion that the Second Amendment is about allowing the citizenry to mount an insurrection against the government is exactly backwards. Rather, it’s about conscripting the citizenry to suppress insurrection.
Andrew Reinbach EXPLAINS:

If somebody brings up the first phrase–” A well regulated Militia, being necessary to the security of a free State…” they [the National Rifle Association, et al] insist the militia meant the people at large, and that the idea was to create a counterweight to the central government, so it wouldn’t dare infringe on the people’s rights.
